Humidity made his rivals feel the heat in the Chesham Stakes thanks to a fine front-running ride from James Doyle at Royal Ascot.
Trained by Andrew Balding, he was an impressive winner in the colours of Cheveley Park Stud over six furlongs at Newbury on debut, but transferred to the ownership of Wathnan Racing ahead of stepping up to seven furlongs for this Listed event.
Humidity (4-1) was quickly away and never passed by his rivals, showing great resolve when challenged late in the day to replicate his brother Holloway Boy, who won this contest on debut at the 2022 Royal meeting.
